The official leethax.net Firefox extension is considered legacy software and is generally not compatible with modern versions of Firefox (versions 57 "Quantum" and later).
The developer has not released a modern "WebExtension" update, meaning the original cheat suite for Facebook and web games (like Candy Crush Saga or Angry Birds) will not work on up-to-date browsers. Status and Alternatives
If you are trying to use Leethax in 2026, here is the current situation based on historical developer updates and community reports:
Mainstream Firefox Compatibility: The extension remains broken for modern Firefox. It relies on an older architecture (XPI) that Mozilla disabled years ago to improve security and performance.
Legacy Browser Workarounds: To use the extension, some users previously used Waterfox (a Firefox fork that maintained legacy extension support) or downgraded to Firefox version 48, though this is strongly discouraged due to severe security risks.
Current Security Warning: Be extremely cautious of any site claiming to have a "new" or "updated" Leethax extension for 2026. Malicious campaigns often use the names of famous legacy tools to distribute credential-stealing malware.
Legitimate Alternatives: There is a modern extension called LeetHub 2.0 on the Firefox Add-ons store, but it is a tool for syncing LeetCode submissions to GitHub and is not related to the leethax.net game cheats. How to check for official updates

Step 3: Disable mandatory extension signing (temporarily).
Step 4: Find a verified fork.

Leethax is a well-known name in the browser gaming community. At its core, it is a cheat engine in the form of a browser extension. It allows users to manipulate specific variables within supported games—such as score, lives, ammo, or time—to make the games easier or to skip levels entirely.
While cheat engines have existed for decades, Leethax gained popularity because of its simplicity. It doesn't require you to be a programmer or understand hex codes. You simply install the extension, load a supported game, and toggle the cheats on or off via a simple menu.
Many veterans argue that a dedicated extension is overkill. The real new Leethax experience on Firefox comes from combining a userscript manager (Violentmonkey or Tampermonkey) with updated Leethax-derived scripts.
